SDP1108-R Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the SDP1108-R?
  Sensirion provides a recommended PCB layout in their application note AN17, which includes guidelines for component placement, routing, and grounding to ensure optimal performance and minimize noise.
• How do I calibrate the SDP1108-R?
  The SDP1108-R is factory-calibrated, but users can perform a zero-point calibration by applying a known pressure (e.g., atmospheric pressure) and adjusting the offset accordingly. Sensirion provides a calibration guide in their application note AN19.
• What is the maximum pressure range for the SDP1108-R?
  The SDP1108-R is designed for differential pressure measurements up to ±10 mbar (±100 Pa). Exceeding this range may damage the sensor or affect its accuracy.
• Can I use the SDP1108-R in a humid or wet environment?
  The SDP1108-R is designed for use in dry environments. Exposure to high humidity or water may affect its performance or damage the sensor. If you need to use the sensor in a humid or wet environment, consider using a protective coating or enclosure.
• What is the response time of the SDP1108-R?
  The response time of the SDP1108-R is typically <10 ms, making it suitable for applications requiring fast pressure measurements.
